Your / filesystem is very full, indicating that very likely you have excess kernel files that can be removed, or possibly you have installed a lot, or A LOT of apps. I'm guessing it's a kernel problem.
Also, while it's your choice, are you using SNAP-based applications on purpose?
To check on the kernel situation, open a terminal, traverse to the /boot directory
Code:
cd /boot
and then enter
Code:
ls -al
.
The output from the ls command should look something like:
Code:
[john@john-HP-ENVY-x360 boot]$ ls -al

If you have significantly more entries than this, then you have a kernel problem, but easily fixable. Otherwise you may have an app problem.
